[0002] In existing technologies, wear-resistant concrete flooring is mainly constructed by pouring large areas of fine aggregate concrete, followed by spreading corundum aggregate on the surface and finishing the surface, and finally cutting the joints. This traditional construction method is not only cumbersome and time-consuming, but also prone to causing numerous uneven cracks in the floor after construction due to uneven heat dissipation within the concrete or improper joint cutting, resulting in high maintenance costs in the later stages of use. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of long construction period, difficulty in quality control, high maintenance cost after construction, complicated procedures and easy ground cracking in the existing construction method of abrasive concrete wear-resistant floor. In order to provide a prefabricated template system for abrasive concrete wear-resistant floor slabs.

[0004] This utility model is achieved through the following technical solution:

[0005] A precast formwork system for wear-resistant concrete floor slabs made of corundum includes longitudinal and transverse reinforcing bars and longitudinal and transverse formwork steel bars. The intersections of the longitudinal and transverse formwork steel bars are connected by cross-shaped clips. Both ends of the longitudinal and transverse formwork steel bars are provided with mortises, and the four ends of the cross-shaped clips are provided with tenons. The mortises at the ends of the longitudinal and transverse formwork steel bars are inserted into the corresponding tenons at the ends of the cross-shaped clips and are fixedly connected by rivets. Several reinforcing bar holes are evenly distributed on the longitudinal and transverse formwork steel bars, and the longitudinal and transverse reinforcing bars are connected to the longitudinal and transverse formwork steel bars through the reinforcing bar holes.

[0006] As a preferred technical solution, the cross buckle is made of four first steel strips welded together in a cross shape. Each first steel strip has a thickness of 10mm and a length of 100mm. The end of each first steel strip is thinned to form a tenon. The height of the tenon is the same as the height of the first steel strip. The tenon has a thickness of 4mm and a length of 20mm.

[0007] As a preferred technical solution, the longitudinal and transverse template steel bars are made of second steel strips with a thickness of 10mm; the two ends of the second steel strips are recessed to form mortises with a groove width of 4mm, a groove wall thickness of 3mm, and a groove depth of 20mm.

[0008] As a preferred technical solution, the rivet is made of a round steel cylinder with a diameter of 5mm and a length of 10mm.

[0009] As a preferred technical solution, rubber strips are bonded and fixed to the top surface of the cross buckle and the top surface of the longitudinal and transverse template steel strips, and the width of the rubber strips is 10mm.

[0010] As a preferred technical solution, stirrup bars are arranged at equal intervals at the bottom of the longitudinal and transverse reinforcing bars.

[0023] To enable those skilled in the art to better understand this utility model, the present utility model will be further described clearly and completely below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] In the description of this embodiment, it should be understood that the terms "longitudinal" and "transverse," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] like Figures 1 to 8 As shown, this embodiment provides a prefabricated formwork system for abrasive concrete wear-resistant floor slabs, including longitudinal and transverse reinforcing bars 4 and longitudinal and transverse formwork steel bars 2.

[0026] Stirrups 10 are arranged at equal intervals at the bottom of the longitudinal and transverse reinforcing bars 4.

[0027] The intersections of the longitudinal and transverse template steel strips 2 are connected by cross-shaped clips 1; both ends of the longitudinal and transverse template steel strips 2 are provided with mortises 5, and all four ends of the cross-shaped clips 1 are provided with tenons 8. The mortises 5 at the ends of the longitudinal and transverse template steel strips 2 are inserted into the corresponding tenons 8 at the ends of the cross-shaped clips 1 and are fixedly connected by rivets 3. In specific implementation, the cross-shaped clips 1 are made of four first steel strips welded together in a cross shape. Each first steel strip is 10mm thick and 100mm long. The height of each first steel strip is determined according to the thickness of the diamond abrasive concrete wear-resistant floor; the end of each first steel strip is thinned to form a tenon 8. The height of the tenon 8 is the same as the height of the first steel strip. The tenon 8 is 4mm thick and 20mm long. A circular rivet hole 7 with a diameter of 5mm is drilled in the center of the side of the tenon 8. The longitudinal and transverse template steel strips 2 are made of second steel strips with a thickness of 10mm. The length of the second steel strip is determined according to the length of the ground separation joints at the construction site, and the height of the second steel strip is determined according to the thickness of the wear-resistant concrete floor. The two ends of the second steel strip are recessed to form mortises 5. The mortises 5 have a groove width of 4mm, a groove wall thickness of 3mm, and a groove depth of 20mm. A circular rivet hole 7 with a diameter of 5mm is drilled in the center of the side of the mortise 5. The rivet 3 is a round steel column with a diameter of 5mm and a length of 10mm. The rivet 3 is inserted into the circular rivet hole 7, which is aligned after the tenon 8 of the cross buckle 1 is connected to the mortise 5 of the longitudinal and transverse template steel strips 2.

[0028] Rubber strips 9, each 10mm wide, are bonded and fixed to the top surface of the cross-shaped clip 1 and the top surface of the longitudinal and transverse template steel strips 2. The rubber strips 9 bonded to the cross-shaped clip 1 and the longitudinal and transverse template steel strips 2 can effectively offset the stress generated by the volume expansion during the hardening process of the concrete after the concrete is poured.

[0029] Several reinforcing bar holes 6 are evenly distributed on the longitudinal and transverse template steel bars 2. The longitudinal and transverse reinforcing bars 4 are connected to the longitudinal and transverse template steel bars 2 through the reinforcing bar holes 6. Since the longitudinal and transverse reinforcing bars 4 are divided into high-position reinforcing bars and low-position reinforcing bars in the longitudinal and transverse directions, the corresponding reinforcing bar holes 6 on the longitudinal and transverse template steel bars 2 are also divided into high-position reinforcing bar holes 6 and low-position reinforcing bar holes 6 in the longitudinal and transverse directions to accommodate the precise passage of the longitudinal and transverse reinforcing bars 4.

[0030] As can be seen from the above description, in the system described in this embodiment, every four cross buckles 1, two longitudinal template steel bars, and two transverse template steel bars can be spliced ​​together to form a set of diamond abrasive concrete wear-resistant floor slab system; each cross buckle 1 can also form a template system with two other longitudinal template steel bars, two transverse template steel bars, and three cross buckles 1 arranged in a quincunx pattern.

[0031] When using the system described in this embodiment to construct a wear-resistant concrete floor, the specific construction steps include:

[0032] 1) First, based on the construction area and equipment conditions, divide the floor into multiple equal or similar storage areas. Place the longitudinal and transverse template steel bars 2 vertically along the storage lines. Then, connect the mortise 5 at the ends of the longitudinal and transverse template steel bars 2 with the tenon 8 of the cross buckle 1 and fix them horizontally with rivets 3.

[0033] 2) Then, the corresponding steel bars in the longitudinal and transverse steel bars 4 are inserted into the longitudinal and transverse steel strips through the steel bar holes 6 in the longitudinal and transverse directions, with each end extending 100mm beyond the steel strip, for connection with the steel bars in the adjacent diamond abrasive ground storage area.

[0034] 3) Finally, following the skip-pour construction method, first pour concrete into the staggered slabs in a quincunx pattern, such as... Figure 9 As shown; the remaining slabs will be poured 3 days later. At the same time, after the concrete of the corresponding slabs has initially set, the corundum aggregate should be spread in time and the surface should be cleaned.

[0035] The embodiments described above only illustrate the preferred implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
